Hi, I'm trying to learn more about streaming video including the different types of players available, the differences in quality, and how they compare to film (35mm) and DVD/blue-ray. Searching online has been difficult since much of the information is public pr stuff as opposed to text-book knowledge.

Right now, I just want to get a sense of where technology is regarding streaming high-quality video. What level of bit-transfer rate is necessary to stream video formats as high as DVD/blue-ray?
